For me this popped in wordament (adventure). You can use your keyboard to type words, which is much faster then using the mouse. I chose a puzzle with a prefix and one star was for using words with that prefix (I had DE) (so more than 1 letter on 1 tile). Use this site:https://words-solver.com/wordament-cheat/
Instead of the prefix use the letter q, you can barely make any words with that letter. Now start finding at least 30 words, without making a word with your prefix. Earn 1 or 2 stars and then click finish puzzle, once you've reached 30+ words as well.
The achievement will pop upon clicking finish puzzle.
